Hi All,
I was able to run my mesh with simpleFoam without a problem, I now want to run it for a compressible turbulent flow case and I have chosen rhoSimpleFoam and sonicFoam as options. but in both cases I get the following error.
Has anyone experienced this before?

Selecting thermodynamics package
{
    type            heRhoThermo;
    mixture         pureMixture;
    transport       sutherland;
    thermo          hConst;
    equationOfState perfectGas;
    specie          specie;
    energy          sensibleInternalEnergy;
}

It seems that the boundary condition for pressure was set to 0.0 and that was causing the problem.

I got the same error, did you fix it?

He explains the fix in the second post ...
